On Update 1.0.5 and later, the developer notes say all actions, including mouse-wheel up and down, can be rebound, and rotation should be rebindable. If a new binding does not work, confirm the version and platform first, remove any conflicting assignment, and test the action outside a crowded factory interaction. Older builds and some Linux middle-mouse settings have separate reported failures, so one workaround is not universal.
Update before changing settings
The strongest current evidence is the Update 1.0.5 note stating that all actions, including wheel directions, can be rebound and that hidden-action conflicts were fixed. An older installation can therefore reproduce limitations that the current guidance no longer assumes. Update, restart the game, and reopen the controls screen before evaluating a failed binding.
Clear conflicts and test one action
Remove any existing assignment that uses the same key or mouse input, then bind one action and apply the setting. Test it in a simple area where the same input is not also being used by a terminal, placement mode, or operating-system gesture. If the action works there, the original failure may be context-specific rather than a global inability to rebind.
Diagnose rotation separately
Community reports discuss holding the middle mouse button and moving the mouse for default rotation, as well as mixed results when rebinding rotation to a keyboard key. The developer stated that rotation should be rebindable, so a current failure is a troubleshooting case rather than proof that the feature is unsupported. Record the selected action, new key, placement mode, and whether the default input still works.
Check Linux middle-mouse behavior
One Linux report recovered rotation after changing a middle-mouse scrolling setting, while another player reported a successful keyboard rebind. Those cases show that system input handling can differ, but neither is a universal solution for Windows or macOS. On Linux, test the desktop or mouse setting only after confirming the game version and preserving the original system setting for rollback.
Collect a reproducible current case
If 1.0.5 or later still rejects a binding, record the operating system, input device, old and new binding, exact action, and whether the controls menu saves the change after restart. Compare mouse-wheel, middle-button, and keyboard inputs separately rather than treating them as one failure. A current reproducible case can support a targeted bug report; without those details, the cause remains 待确认.
